I love this. I use it every day. It's great. The thermous part of it is great. This keeps my water chilled for nearly a day.I love the temperature and the ease of use with the electric top. Even better that I know my water is filtered and clean, saves me from drinking plastic bottled water.Is it purified? I do not know. But my brain thinks it is, and that is all that matters to me.

I only drink water straight from the tap and never have problems with taste, freshness and contamination in our area but sometimes I do worry if it’s the case all the time as we can’t see germs. This is really revolutionary especially when you are not familiar in the area and bottled water is not available. Very easy to use and operate. Bottle looks nice and durable and easy to clean. Can be use used hot and cold. Will be using this when camping and when travelling. I love that it can also tell you the temperature. I think it’s a good product but to see if it works 100% is not something I can prove as I have no ability or tool to test the water.

This water bottle is very expensive at first look but comes with features to support this price point. Firstly as a flask it is very good at keeping drinks hot or cold. I put a coffee in it and it was still at a warm drinking temperature the next morning. I’m not sure entirely how accurate the temperature sensor is, water straight out my fridge set at 3 degrees never shows as colder than 7 degrees in the bottle. Despite this it’s a good indicator of how hot or cold the contents are.The drink reminder function seems to be a bit fo a gimmick to me. I would just have a drink when I feel thirsty rather than needing a reminder although it may be useful to some people. It would be nice to be able to customise the interval between reminders.The main selling point is the UV sterilisation. This feature could prove invaluable if you need drinking water but aren’t sure of the quality of a water source. Just fill your bottle up and set the strerilisation and it cleans the water for you. Without scientific testing of your own it would be difficult to tell how effective this is on the water you use it with but it is bound to be better than just drinking water that you suspect not to be very clean. This provides an alternative to lugging around large quantities of bottled water when hiking, trekking or wild camping.

This bottle has some interesting features to it.I like the temperature sensor, and it is quite accurate as I sometimes mix hot and cold water and I notice the temperature go down over time.The UV cleaning function is fantastic. It's hard to tell if it is fully effective, but I presume it is.One downside is that the functions are quite sensitive to touch, so may be pressed unintentionally.The diameter of the mouth of the bottle is also a bit smaller than others, so the bottle needs to be tilted more than the average bottle, this results in a few more spills than usual. But after getting used to this, it does reduce.

This is a very smart looking bottle with a brushed black finish. With a 500ml capacity it's smaller than a typical thermos flask but similar to many plastic water bottles available. This retains heat well, similar to a thermos, and has a temperature gauge built in to the lid.The interesting feature is the UV option, which should inactivate bacteria and viruses, effectively sterilising the contents. A friend of mine has a UV system which sterilises water from a stream running past his property as he has no mains water, and confirms how well UV is at making water drinkable. Of course in this case it's impossible to tell how well this works without testing the water after sterilisation, but assuming that this works as it should it provides a good option for making water drinkable rather than by adding chemicals.At around £40 this is an expensive water bottle, so is very much a niche product for someone that needs to sterilise their fluid.
